Post by: gypsie on October 05, 2014, 07:54:06 PM
Hello everybody.

One of my X68000 compact do not have video signal (no picture,black screen).

I ve tested it with a working psu.

I will try to change caps on the video circuit  but not sure they re faulty.

Do you know which parts of the video board i must check ?

Thanks

Hi x-col.

My X68030 had the same problem, I opened the video module and there was some caps leaking.
I replaced them all and got video back working.

So, that would be my suggestion... after all, replacing caps won't hurt, you may want to do some day anyway.

 Hi Gypsie !

Replace all of them. They are way past their expected lifetime anyway.
